Week 1: Applying principles of Learning Theory and the study and measurement of behaviour Flashcards
A type of associative learning demonstrated in 1899 by Russian physiologist, Ivan Pavlov.
Classical Conditioning
The Theory of _______ __________ explains how reflex behaviour may become associated with a new stimulus that does not naturally activate that behaviour.
Classical Conditioning
What are the five elements of classical conditioning?
Unconditioned stimulus (UCS)
Unconditioned response (UCR)
Neutral stimulus (NS)
Conditioned stimulus (CS)
Conditioned response (CR)
In Pavlov’s original experiment on classical conditioning, the conditioned stimulus (CS) was:
a) salivation elicited by the meat powder
b) the meat
c) salivation elicited by a tone
d) the sound of a tone
d) the sound of a tone
Hali is enjoying fish and chips for dinner while watching ‘The Bachelor’. A few hours later she is feeling nauseous and experiences food poisoning. The next week when she sits down to watch ‘The Bachelor’ she feels nauseous. ‘The Bachelor’ is…
a) The unconditioned stimulus (UCS)
b) The conditioned stimulus (CS)
c) The conditioned response (CR)
d) The unconditioned response (UCR)
b) The conditioned stimulus (CS)
What is an Unconditioned Response (UCR)? You can choose more than one answer.
a) It is usually a reflex and response of the autonomic nervous system
b) Presenting it results in UCR occurring
c) It is an innate or unlearned response to the UCS.
d) It involuntarily elicits the UCR
a) It is usually a reflex and response of the autonomic nervous system
c) It is an innate or unlearned response to the UCS.
Little Albert’s Fear of white rats is an example of __________conditioning.
classical
____________is the decreasing strength of a response after repeated exposure to a stimulus?
Habituation
Something that elicits a response or reaction?
Stimulus
Classical conditioning was discovered from which experiment in the 1890s?
Pavlov’s dog experiment
EXCESSIVE and IRRATIONAL fear of
an object, place or situation
Phobia
Before conditioning:
Unconditioned Stimulus elicits ______ Response,
Neutral Stimulus does not (no response)
Unconditioned
During conditioning: Repeated pairing of Unconditioned Stimulus & Neutral Stimulus results in ________ response.
Unconditioned
After conditioning:
Neutral Stimulus is now a Conditioned Stimulus,
which elicits a _______ Response.
Conditioned
The Unconditioned Response (UCR) is
- an innate or unlearned response to the UCS.
- usually reflexive & a response of the autonomic nervous system. True/False
true
Reflex behaviour is voluntary/involuntary?
Involuntary
(arises automatically in response to an appropriate stimulus, e.g. salivating at the smell of food, feeling fear when facing a frightening situation)
Emotional responses can/cannot be learned through classical conditioning.
can
(both positive and negative emotional responses can
be learned or conditioned)
Temporal or spatial pairing of the 2 stimuli (CS & UCS).
Reinforcement
Initial stage of learning something
Acquisition
Usually several pairings of the CS and UCS are needed before the CR is fully developed.
True/False
True
(the first series of CS-UCS pairings, and gradual appearance and strengthening of the CR occurs
during the acquisition phase of the experiment.
* Proceeds more quickly if the intensity of the UCS increases (i.e., a louder bell or tone; a stronger
puff of air)
This procedure produces a reduction and eventual disappearance of the CR. and involves repeatedly presenting the CS without the UCS
Extinction
e.g. If a dog salivates at the sound of a tone, after the acquisition phase, this salivation response will
gradually disappear if the tone is presented for many trials without food being delivered.
* When extinction is completed, no salivation will occur if the tone occurs.
The “reappearance of an extinguished response after a period of nonexposed” to the CS
Spontaneous Recovery
(conditioned responses have reappeared.
* Extinction does not simply “erase” the previous learning, or permanently “destroy” the CS—UCS
pairing)
After classical conditioning with a CS, the most similar stimuli will also elicit CRs, even though they have
never been paired with the UCS.
Generalisation
e.g. Tones of different frequencies may still elicit a CR, or different bells might elicit salivation
The opposite of generalisation and very important in the “real world” the subject learns to respond to one stimulus and
not to a similar stimulus.
Discrimination
(Impala (African antelopes) can learn to discriminate between African wild dogs (predators) that
have just eaten (& won’t attack) and hunting/hungry African wild dogs (very dangerous). Hungry
wild dogs elicit fear responses, but those that have eaten do not)
